Title: Prevention of auto-ignition in end gas regions of a cylinder of a gasoline spark-ignition i.c engine
Inventor: THOMAS TSOI HEI
IPC: F02D41/02
Filed: 1997-10-09
Abstract: A gasoline spark ignition internal combustion engine has homogeneous fuel separated into a lighter vapour fraction 110 and a heavier liquid fraction 112; the two fractions being introduced to the intake air separately so as to produce a stratified charge under full load conditions. The lighter vapour fraction 110 is positioned near the spark plug 106 and the heavier vapour fraction 112 is positioned at the end gas regions which tend to be, but not necessarily are, located near the cylinder walls. The lighter vapour fraction 110 has a low ignition point and ignites easily from the spark creating a flame kernel. The heavier liquid fraction 112 in the end gas regions has a lower ignition temperature allowing the fraction to resist auto-ignition as the temperature and pressure rises as a result of the ignition of the lighter fuel fraction and to only ignite when the flame front of the kernel arrives.

Title: PC server telecommunications power system
Inventor: ZORELLA PETER
IPC: H04M19/00
Filed: 1997-11-12
Abstract: A ringing voltage (75 VAC) for telecommunications cards 5 within a PC server cabinet 1 is generated from an externally supplied loop feed voltage (-48 VDC) by means of a ringer module 9 housed within a metal container which is mounted in a standard sixe bay, or in an ISA or PCI card-slot, of the PC server cabinet. The arrangement limits accidental user exposure to hazardous ringing signal voltage levels. As an additional safety measure, the ringing voltage output from the module 9 may be interrupted for 1 second when the module output has been loaded for 5 seconds, thereby ensuring that in the event of accidental human exposure, escape is possible when the output is interrupted. The ringer module 9 may be coupled to an external -48 VDC supply 6 via D-type connectors (Fig.2), the male connector (7B) having some pins removed and the female connector (7A) having corresponding holes blocked to prevent coupling to unmodified connectors.

Title: An iron sole plate
Inventor: BOULEAU JEAN-PAUL
IPC: D06F75/38
Filed: 1998-01-14
Abstract: A sole plate for an electric iron, designed to be fixed to a heating body, comprises a metal sheet having an internal face for thermal contact with the heating body, and an external face often referred to as the ironing face. The external face is characterised by reliefs, formed by a plurality of protrusions (10) distributed over practically its entire surface, where each protrusion may have the general shape of a truncated cone, or a truncated polygonal shape with inclined faces. The tops (11) of the protrusions lie for the most part in a common plane (P), each with a plane surface lying in the range from 7 thousands of a mm<SP>2</SP> to 20mm<SP>2</SP> and with a height, from the base (14), lying in the range from 2 hundredths of a mm to 1mm. The protrusions thus form a network of intersecting channels (12), which increase the performance of the iron, in that they aid the supply of steam to an article being ironed, whilst assisting the sliding of the iron over the article. The aesthetic appearance of the iron is also improved, as the sole plate is scratch resistant, and keeps a shiny appearance.
Patent GB-2324169-A (GB)
Title: Producing corrected masks for use in making semiconductors
Inventor: OHNUMA HIDETOSHI
IPC: G03F1/68
Filed: 1998-04-06
Abstract: A method for correcting designed-pattern data obtained by data-processing a plurality of designed patterns for use in making masks, comprising the steps of (a) producing hierarchical-area-bitmapped bitmap data from a plurality of the designed-pattern data, (b) determining a line width of the designed pattern and a space width between said designed pattern and a designed pattern adjacent to said designed pattern, from said hierarchical-area-bitmapped bitmap data, and (c) correcting the designed-pattern data on the basis of the determined line width and the determined space width, for proximity effect correction and/or optical proximity effect correction in order to produce a corrected mask for use in semiconductor production. Step (a) is performed by breaking the data down into a first grid size of 16 pixels each and determining whether a pattern is totally present (designated '11') totally absent (designated '00') or partially present (designated '01'). If partially present, this data is broken down into a smaller second grid size and if still partially present in this grid, it is further broken down into a smaller third grid size (see Fig 2B).

Title: Thrust sensor
Inventor: SANDERS PETER GEORGE
IPC: H02K11/00
Filed: 1998-04-20
Abstract: A thrust sensor assembly for use with an actuator of the type wherein motive power is applied to an actuator shaft (2), comprises first and second compression plates (11, 12), one plate being on or adapted to engage directly or indirectly through an intermediate member with the shaft to move axially with the shaft, the second compression plate opposing the first compression plate with resiliently compressible pad(s) (16, 17) sandwiched therebetween. A pressure transducer (18) is mounted on one of the compression plates, whereby movement of the first plate towards the second compresses the pad(s) between the two plates and the pressure transducer inducing a signal from the transducer that corresponds to the thrust of the shaft. The total contact area of the compressible pad(s) is selectively variable by replacing the pad or pads with larger or smaller pads or using a different number of identical pads, whereby a range of actuator thrusts may be accommodated by a single pressure transducer.

Title: Anti-aliaising method using sub-sample pixels and corresponding sub-scan lines
Inventor: BARKANS ANTHONY C
IPC: G06T11/20
Filed: 1998-07-01
Abstract: A method and apparatus for generating a mask (126) identifying a number of subsamples (sub0, sub1, sub2, sub3) of a pixel (73) that are covered by a primitive (74) includes the process of apportioning an image, comprising a plurality of scan lines into a plurality of sub-scan lines (sub-scanline0, sub-scanline3, sub-scanline5, sub-scanline7), such that a number of sub-scan lines crosses each pixel (73). A sample point (sub0, sub1, sub2, sub3) is placed on at least one of the sub-scan lines. To determine the number of samples that are covered by a primitive, edge stepping (52) is used to step along each edge (edge1, edge2, edge3) of the primitive (74), generating a sub-scan line coordinate for the edge. The edge stepping hardware (52) is used for stepping either on a sub-scan line granularity, for operation in anti-aliased mode, or on a scan line granularity, for operation in aliased mode. In anti-aliased mode, as each edge sub-scan line coordinate is generated, it is compared (89) against the coordinates of a sample point on that sub-scan line, to determine whether or not that sample point is covered by the primitive. A mask (126) is generated for each pixel, with each bit of the mask corresponding to one of the sub-scan line samples. A bit in the mask is set if the subsample is covered by the primitive. Thus, a mask (126) representing covered subsamples is provided by using incremental techniques to approximate a percentage of pixel coverage without the complex hardware and lookup tables used in the prior art.

Title: Optical fibre coupling system
Inventor: JUNGERMANN ROGER LEE
IPC: G02B6/30
Filed: 1998-08-14
Abstract: A system (10) for coupling an optical signal into an optical fibre having a high insertion loss repeatablility, includes a lens (12) for receiving an applied optical signal and for magnifying the beam diameter of the optical signal by a magnification factor. The bottom surface (24) of a glass plate (22) intercepts the expanded beam (11), and a well (26) is formed on top of this glass plate (22) for receiving an end of the optical fibre (18). The well (26) also contains an index matching fluid (25), interposed between the end of the optical fibre (18) and the glass plate (22). Finally a positioning mechanism (21) positions the optical fibre (18) at a predetermined location in the well (26) to within a positional tolerance and an angular tolerance, the magnification factor of the lens (12) being chosen according to the positional and angular alignment tolerances, so that the insertion loss is within a predefined range. Rather than a well (26) containing index matching fluid (25) formed on top of the glass plate (22), a housing (56, fig. 3) having a hole adjacent to a top surface (23) of the glass plate (22), for receiving an end of the optical fibre (18), may be placed above the glass plate (22). A gasket (54, fig. 3) may then be positioned between the housing (56) and the glass plate (22), whilst index matching fluid (25) is provided in the hole of the housing (56) between the end of the optical fibre (18) and the glass plate (22). A capillary tube may also be used to contain the index matching fluid (25), or a reservoir may be used to hold the fluid (25), into which multiple bare fibres (18, fig. 3) may be inserted, with an optical thermal management system controlling the temperature of the index matching fluid (25) in order to reduce optical signal reflections. Such a system may be used to couple optical signals into bare fibres of optical components, in order to measure their performance parameters before they are installed into wavelength division multiplexed systems.

Patent GB-2328538-A (GB)
Title: Sense amplifier
Inventor: PROEBSTING ROBERT J
IPC: H03K3/356
Filed: 1995-10-02
Abstract: An amplifier comprises first and second input transistors 14,22 and cross coupled third and fourth output transistors 54, 70 wherein the first and second transistors have greater current capacity than the third and fourth transistors. Transistors 54 and 70 are two thirds the width of transistors 14 and 22. A first amplifier stage 14, 22, 54, 70 is biased to minimise current consumption of all stages of the amplifier and to provide outputs of the first stage that are high enough in voltage to allow proper operation of a second stage 100, 104, 108, 112 of the amplifier, yet low enough in voltage to allow a current mirror to be integrated into the second stage of the amplifier. The integration of the current mirror into the second stage amplifier reduces capacitive loading on the outputs of the second stage increasing speed while eliminating the extra power normally associated with a separate current mirror. If the voltage gain of the first stage amplifier is not necessary the second stage may be used as a first stage with the inputs to the circuit going directly to the gate terminals of transistors 100 and 104.
